SYNOPSIS

DESCRIPTION

This manual page documents briefly the acpidump , acpixtract , turbostat and madt commands. acpidump and acpixtract options are described below while madt can only read an APIC table from standard input.

turbostat reads hardware registers and gather statistics on the processor clock frequency and C-state usage. Works properly on Nehalem and newer processors and on Linuxkernel 2.6.30 and later versions.

OPTIONS

acpidump options are as follow:

-a, --addr 0x1234

look for tables at this phisical address

-t, --table DSDT

only dump table with DSDT signature

-o, --output filename

redirect output from stdin to filename

-b, --binary

dump data in binary form rather than in hex-dump format

-l, --lenght 0x456

works only with --addr, dump phisical memory region without trying to understand it's contents

-s, --skip 2

skip 2 tables of the given name and output only 3rd one

-h, --help

outputs an help message

acpixtract only option is:

-n instance_number

prints Nth instance of target table, default is 1

OPTIONS

acpixtract options are as follow:

-a

extract all tables, not just DSDT/SSDT

-l

list table summaries, do not extract

-s<Signature>

Extract all tables named <Signature>

OPTIONS

turbostat options are as follow:

-v

makes turbostat more verbose

-i <sec>

polling interval, default is 5

When given a command turbostat runs it and outputs statistics gathered while the program was running.

EXAMPLES

Dump the DSDT table to the file DSDT.aml in binary format (this can be disassembled later with iasl(1):
